摘要
Anionic iron(0) tetracarbonyl with terminal phenyltellurolate ligand PhTe − , [PhTeFe(CO) 4 ] − , has been synthesized and characterized. The title compound was obtained by addition of (PhTe) 2 to [PPN][HFe(CO) 4 ] THF solution dropwise. [PPN][PhTeFe(CO) 4 ] crystallizes in the monoclinic space group C c, with a = 16.119(4) Å, b = 13.141(3) Å, c = 19.880(8) Å, β = 93.04(3)°, V = 4205(2) Å 3 , and Z = 4. The [PhTeFe(CO) 4 ] − anion is a trigonal‐bipyramidal complex in which the phenyltellurolate ligand occupies an axial position with Fe‐Te bond length 2.630(5) Å and the Fe‐Te‐C(Ph) angle is 103.4(5)°. The neutral iron(0)‐telluroether compound, (PhTeMe)Fe(CO) 4 , was prepared by alkylation of the [PhTeFe(CO) 4 ] − . Protonation of [PhTeFe(CO) 4 ] − and reaction of H 2 Fe(CO) 4 and PhTe) 2 ultimately lead to formation of the known dimer Fe 2 (μ‐TePh) 2 (CO) 6 and H 2 .
